1、产前和产后联合阻断HBsAg阳性孕妇母婴传播的研究【摘要】目的评价产前和产后联合阻断措施,对乙型肝炎表面抗原(HBsAg)阳性孕妇母婴传播的阻断效果。方法将乙型肝炎表面抗原(HBsAg)阳性的孕妇在产前检查时随机分为两组,人乙型肝炎免疫球蛋白(HBIG)组:HBsAg、HBeAg双阳性组孕妇产前4个月(妊娠24周起)每4周肌肉注射HBIG200IU直至临产;HBsAg单阳组孕妇产前3个月(妊娠28周起)每4周肌肉注射HBIG200IU直至临产;对照组孕妇不注射HBIG。两组所生新生儿于出生后2h内及2个月取股静脉血,检测乙型肝炎病毒感染
2、标志HBVM。双阳性组母亲分娩新生儿每10天肌肉注射HBIG200IU,单阳组母亲分娩新生儿每15天肌肉注射HBIG200IU。结果HBIG组母亲所生新生儿宫内感染率为2.6%,2个月时具有保护性抗体有效保护率为95.6%;对照组母亲所生新生儿宫内感染率为39.3%,2个月时具有保护性抗体的有效保护率为76.4%,宫内感染率比较χ2=3.86,P<0.05。结论产前和产后联合阻断乙型肝炎病毒的母婴传播有效保护率达到95.6%,能明显减少宫内感染的发生,获得目前最大限度的提高对乙型肝炎病毒母婴传播的阻断作用。【关键词】乙型肝炎病毒母
